Upgradeability alone is not a finding — every serious protocol is upgradeable. The finding is who holds the key and how much warning holders get. This endpoint reads the proxy pattern from the EIP-1967 slots, the clone bytecode or an implementation() call, resolves the admin, checks whether that admin is a multisig by asking it for its threshold and signer count, and checks whether it is a timeloc

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
